NPA means non - peroxide activity. This non-peroxide activity is found only in some Manuka Honey.

Manuka tree is found throughout New Zealand and often forms extensive areas of bush. The leaves are dotted with oil glands, and when bruised give off a gingery peppery smell. The flowers vary from brilliant white through to rose-pink. The Maori people used Manuka as a medicinal plant, from treating fevers and colds to sedatives. Early European settlers called it the "tea tree." Manuka honey contains a number of natural compounds with strong antibacterial properties. This is a strong flavoured honey, but with a fresh, clean bite.
